Hybrid tea rose plant named ‘KORcripoco’

ABSTRACT

‘KORcripoco’ is a new and distinct variety of  Rosa hybrida  which is characterized by the combination of an upright growth habit and large, very-double flowers with cream centers and pink edges. The new variety propagates successfully by grafting and by stem cuttings and has shown to be uniform and stable in the resulting generations from asexual propagation.

Latin name of genus and species: The Latin name of the genus and speciesof the novel variety disclosed herein is Rosa hybrida.

Variety denomination: The inventive variety of Rosa hybrida disclosedherein has been given the variety denomination ‘KORcripoco’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Rosa hybrida, hybridtea rose cultivar, which has been given the variety denomination of‘KORcripoco’. Its market class is PLT/130.

Parentage: The Rosa hybrida variety ‘KORcripoco’ is the result of acontrolled cross-pollination breeding program carried out by theinventor in Offenseth-Sparrieshoop, Germany. The objective of the saidbreeding program was to create a new and distinct rose plant with uniquequalities, such as:

-   -   1. Uniform growth and flowering;    -   2. Abundant attractive, recurrent flowers;    -   3. Attractive and abundant foliage; and    -   4. Resistance to diseases encountered in landscapes and gardens.        This combination of qualities is not present in prior rose        cultivars known to the inventor. These objectives have been        substantially achieved and in that distinguish ‘KORcripoco’ from        all other varieties known to the inventor.

‘KORcripoco’ is a seedling selection which resulted from the controlledpollination of an unnamed breeding line developed and owned by the sameinventor, the seed parent, and Rosa hybrida ‘KORquelda’ (U.S. Plant Pat.No. 17,048), the pollen parent, during the summer of 2002.

As part of a rose development program, Tim-Hermann Kordes germinatedseeds from the aforementioned hybridization during the following winterand conducted evaluations and observations on the resulting seedlings ina controlled environment in Offenseth-Sparrieshoop, Germany. Theresulting seedlings exhibited distinctive physical and biologicalcharacteristics. The new rose plant was selected as a single plant inMay of 2003 from the seedling beds due to its superior characteristicsand asexually propagated for further evaluation. This new anddistinctive rose variety was given the name ‘KORcripoco’.

Asexual Reproduction: The first asexual propagation of ‘KORcripoco’ wasperformed in July of 2003 at the inventor's nursery inOffenseth-Sparrieshoop, Germany. Subsequently, ‘KORcripoco’ has beensuccessfully propagated by stem cuttings and grafting in Jackson County,Oreg. These initial and other subsequent propagations conducted incontrolled environments demonstrate that ‘KORcripoco’ reproduces true totype in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following characteristics have been repeatedly observed andrepresent the distinguishing characteristics of the new Rosa hybridacultivar ‘KORcripoco’. These traits, in combination, distinguish‘KORcripoco’ as a new and distinct cultivar.

-   -   1. Rosa hybrida ‘KORcripoco’ exhibits an upright growth habit;        and    -   2. Rosa hybrida ‘KORcripoco’ exhibits an abundance of flowers        born singularly and in clusters; and    -   3. Rosa hybrida ‘KORcripoco’ exhibits a very-double flower        habit; and    -   4. Rosa hybrida ‘KORcripoco’ exhibits a large flower size; and    -   5. Rosa hybrida ‘KORcripoco’ exhibits flowers with cream-colored        centers and pink edges, at anthesis; and    -   6. Rosa hybrida ‘KORcripoco’ exhibits very good disease        resistance.

COMPARISONS WITH THE PARENTS

The new rose plant may be distinguished from its seed parent, an unnamedseedling, by the following combination of characteristics:

-   -   1. ‘KORcripoco’ exhibits flowers with cream centers and pink        edges, whereas the seed parent exhibits flowers with yellow        centers and red edges.    -   2. ‘KORcripoco’ exhibits medium plant height, whereas the seed        parent exhibits a tall plant height.

The new rose plant may be distinguished from its pollen parent, Rosahybrida ‘KORquelda’, by the following combination of characteristics:

-   -   1. ‘KORcripoco’ exhibits flowers with cream centers and pink        edges, whereas ‘KORquelda’ exhibits a yellow flower color.    -   2. ‘KORcripoco’ exhibits a more upright plant habit, whereas        ‘KORquelda’ exhibits a more bushy habit.
